non-porous material which only has external surface. The
BET surface area of SrFe12O19 MNPs was calculated as 10.4

Conclusion
In conclusion, our work presents the synthesis of SrFe12O19
nanoparticles and its new application as a green magnetic
Lewis acid catalyst for the synthesis of a-aminobenzylphenols
through the solvent-free Betti reaction. The SrFe12O19 nano-
particles can be separated from the reaction mixture by the
use of an external magnet and also are recyclable which
makes it as an eco-friendly catalyst.
